What follows is a quote from Scott's seminal paper on formal semantics, in which he mentions the "operational" aspects of semantics. Gordon Plotkin introduced the structural operational semantics, Robert Hieb and Matthias Felleisen the reduction contexts, [2] and Gilles Kahn the natural semantics. Structural operational semantics also called structured operational semantics or small-step semantics was introduced by Gordon Plotkin in Plotkin81 as a logical means to define operational semantics.

The basic idea behind SOS is to define the behavior of a program in terms of the behavior of its parts, thus providing a structural, i. An SOS specification defines the behavior of a program in terms of a set of transition relation s. SOS specifications take the form of a set of inference rules that define the valid transitions of a composite piece of syntax in terms of the transitions of its components.

For a simple example, we consider part of the semantics of a simple programming language; proper illustrations are given in Plotkin81 and Hennessy90 , and other textbooks. Such a definition allows formal analysis of the behavior of programs, permitting the study of relations between programs.

Important relations include simulation preorders and bisimulation. These are especially useful in the context of concurrency theory. Thanks to its intuitive look and easy-to-follow structure, SOS has gained great popularity and has become a de facto standard in defining operational semantics.

As a sign of success, the original report so-called Aarhus report on SOS Plotkin81 has attracted more than citations according to the CiteSeer [2] , making it one of the most cited technical reports in Computer Science.

Reduction semantics are an alternative presentation of operational semantics using so-called reduction contexts. The method was introduced by Robert Hieb and Matthias Felleisen in as a technique for formalizing an equational theory for control and state. For example, the grammar of a simple call-by-value lambda calculus and its contexts can be given as:. The shape of the contexts indicate where reduction can occur i.

To describe a semantics for this language, axioms or reduction rules are provided:. This single axiom is the beta rule from the lambda calculus. The reduction contexts show how this rule composes with more complicated terms. In this case, the contexts uniquely decompose terms so that only one reduction is possible at any given step.

Extending the axiom to match the reduction contexts gives the compatible closure. Taking the reflexive, transitive closure of this relation gives the reduction relation for this language. The technique is useful for the ease in which reduction contexts can model state or control constructs e. In addition, reduction semantics have been used to model object-oriented languages, [3] contract systems , and other language features. Big-step structural operational semantics is also known under the names natural semantics , relational semantics and evaluation semantics.

One can view big-step definitions as definitions of functions, or more generally of relations, interpreting each language construct in an appropriate domain. Its intuitiveness makes it a popular choice for semantics specification in programming languages, but it has some drawbacks that make it inconvenient or impossible to use in many situations, such as languages with control-intensive features or concurrency.

A big-step semantics describes in a divide-and-conquer manner how final evaluation results of language constructs can be obtained by combining the evaluation results of their syntactic counterparts subexpressions, substatements, etc. There are a number of distinctions between small-step and big-step semantics that influence whether one or the other forms a more suitable basis for specifying the semantics of a programming language. Big-step semantics have the advantage of often being simpler needing fewer inference rules and often directly correspond to an efficient implementation of an interpreter for the language hence Kahn calling them "natural".

Both can lead to simpler proofs, for example when proving the preservation of correctness under some program transformation. The main disadvantage of big-step semantics is that non-terminating diverging computations do not have an inference tree, making it impossible to state and prove properties about such computations. Small-step semantics give more control of the details and order of evaluation. In the case of instrumented operational semantics, this allows the operational semantics to track and the semanticist to state and prove more accurate theorems about the run-time behaviour of the language.

The fact that a deductive argument is valid cannot, in itself, assure us that any of the statements in the argument are true; this fact only tells us that the conclusion must be true if the premisses are true.

They offer a fun way to create an obstacle for the heroes without having them need to use violence to overcome this obstacle.
